Am comirrroizmo nmcn This invention relates to air conditioning dehydratin efl'ect.

Air con itioning devices for small enclosures as have been heretofore provided, have necessitated electric motors, pumps, and refrigerating equipment to such an extent as to render their cost prohibitive. Also, cooling devices which employ large quantities of water ice over which air is blown by an electric fan are objectionable because of the cost of the ice, about 300 lbs. a day being needed; and because of the inconvenience in handling the large quantities of water resulting from the melting of the water ice. Also,the blow ing of air over water ice causes an excessive amount of water in the air, which is undesirable and a source of discomfort.

It is, therefore, an object of this invention to rovide a simple and inexpensive air con ditloning device which requires no refrigeretlng equipment or large quantities of water ice.

A further object is the revision of an air conditioning device in w ch solidified car--' bon dioxide is used as the cooling medium, andwater from the atmosphere is condensed on metal vanes chilled to a.- very low degree by the solidified carbon dioxide. 7

A further object is the provision of a simple, portable air conditionin device which requires very little attention, and which may be operated from the usual household electric light circuits.

A. further object is the rovision oi an air conditioning device whic may be conveniently moved from room to room; and which effectively distributes cool, dehydrated air to Application fled September a, 1932. semi Io. 881,787.

all parts of a room b convection and by means of a blower w ich forces air over metal vanes chilled by a refrigerant such as sglidified carbon dioxide, water ice, or the A further ob'ect is the provision of an air conditioning evice which has associated therewith a refri erated compartment conveniently dispose and arranged for chilling beverages, foods and the like; or for use by physicians, pharmacists, photo aphers, etc., for chilling medicines, vchemica compounds, etc. v

These and other objects are attained by the novel construction, combination and ar- 65.1

rangement of parts hereinafter described and shown in the accompanyin drawings, constituting a material part-o this disclosure, and in which:

Fig. 1 is a perspective view of the exterior of the air conditioning device.

Fi 2 is a longitudinal sectional view showing details of the interior of the device.

Fig. 3 is a transverse sectional view of the device. Y

Fig. t is a perspective view showin a refrigerant receiving chamber integra y attached thereto.

Referring to the drawings, the air conditioning device is shown to include a cabinet having a removable front wall 5, side walls 6,

a rear wall 7, and a removahlecover 8, the cabinet-being mounted upon casters 9 to enable to it be convenientlymoved from room. to room.

Positioned in the cabinet is a casing 10, preferably made of metal, said casing having a lower compartment ll which is water tightso that it can safely hold condensed water received from the atmos ohere.

The front oi the casing is provided with an openin communicating with an air duct- 12 into ra connected with the casing and upwar ly directed, the mouth of the air duct 1 registering with a plurality of spaced openins's 1.3 in the front wall 5 of the cabinet.

lhe rear wall of the casin it) has an o en-v ing 14 in which is positioned a fan 15 o the blower type, said fan being operated by an electric motor 16, the latter being mounted 7 cabinet, said casing having an upper compartment and a lower compartment, a plurality of vertical corrugated vanes suspended from the bottom of the upper compartment, said vanes being in alinement with the openings in the walls of the casing, a quantity of a refrigerant such as solidified carbon dioxide positioned in the n per compartment and means for blowing a raft of air over sai vanes.

' 2. In an air conditioning device, a compartment having a bottom made of a good heat conducting material, said compartment beingadapted to hold a quantity of a refrigcrating substance, a plurality of vertical partment and a lower com artment, a plurality of vanes suspended cm the bottom of the upper compartment, said upper compartment being adapted to receive a quantity of a refrigerating substance, and means for blowing a draft 0 air over said vanes.

spaced chambers in communication with each other and with the compartment, the walls of said chambers being vertical and directly connected to the bottom of the compartment, and a plurality of vertical vanes directly connected to the bottom of the compartment, said .vanes and the walls of the chambers being made of a good heat conducting material. 3. In an air conditioning device, a casing having an opening in its rear wall, an air duct attached to the front wall of and communicating with the interior of the casing a compartment mounted in the casing an' having a bottommade of a good heat con- 3o ducting material, said compartment holding a quantity of solidified carbon dioxide, a plu--.

rality of vertical metal corrugated vanes directly connected to the bottom of the compartment, means for blowing a draft of air tached to the rear wall of the casing, and a coil of tubing positioned in said second compartment, said tubing communicatin with the first compartment to receive cold 40 'sublimed carbon dioxide gas to chill the sec- 0nd compartment so that the latter may be used for chilling beverages, foods and the like.
